Abstract

Abstract

This study aims to design a training program using specific (targeted) exercises to improve certain physical and biomechanical variables associated with the take-off phase, as well as to enhance the performance level of long jump athletes. Three main hypotheses were tested, proposing statistically significant differences between pre- and post-test measurements in physical variables, biomechanical variables, and performance outcomes following the application of the program.

Measurements were conducted on a sample of athletes, and the results revealed notable improvements in physical variables such as vertical jump (14.29%), approach speed over the last 10 meters (7.3%), explosive step-up repetitions (30%), and standing broad jump distance (13.95%). Biomechanical variables also showed significant enhancement, particularly in the take-off angle (23.53%), elevation of the center of mass during take-off (50%), and a reduction in ground contact time (26.32%). These developments were reflected in an overall improvement of 8.62% in long jump performance.

In light of these findings, the researcher recommends integrating specific training exercises into both physical and technical preparation programs for long jumpers. Emphasis should also be placed on biomechanical assessments as performance indicators to better guide the training process. Further studies are encouraged across different age categories and additional kinematic variables to support continued advancement in long jump performance.
